Back surgery KOs Richardson

Knicks forward Quentin Richardson underwent back surgery and will miss the rest of the season. His recovery will take about three months.

Richardson "is expected to resume a normal NBA career," according to a doctor. Doctors removed fragments from a herniated disc, the Knicks said.

Richardson missed the last seven games because of chronic back trouble.
